Bruxism Test

Q: What is bruxism?

Bruxism is the medical term for grinding, gnashing, or clenching your teeth. It can occur during sleep (sleep bruxism) or while awake (awake bruxism). Chronic teeth grinding can damage teeth, cause jaw pain, and lead to headaches and other complications.

Q: How do I know if I grind my teeth at night?

Signs of nighttime teeth grinding include waking with jaw soreness, dull headaches, worn tooth enamel, increased tooth sensitivity, tight jaw muscles, disrupted sleep, and a bed partner reporting grinding sounds. Your dentist may also notice signs during routine examinations.

Q: What causes teeth grinding?

Bruxism causes include stress and anxiety, sleep disorders (like sleep apnea), abnormal bite or misaligned teeth, missing or crooked teeth, certain medications (especially antidepressants), lifestyle factors (caffeine, alcohol, smoking), and genetic predisposition.

Q: How is bruxism treated?

Treatment options include custom night guards to protect teeth, stress management techniques, correcting bite alignment, treating underlying sleep disorders, reducing caffeine and alcohol intake, jaw exercises and physical therapy, and in some cases, medication or Botox injections.

Do you wake up with jaw pain or headaches? You might be grinding or clenching your teeth. Take this quick test to assess your bruxism risk and discover if you need a night guard or other treatment.

Question 1 of 12 8%

Understanding Bruxism (Teeth Grinding)

Bruxism affects an estimated 8-31% of the population, with many people unaware they grind their teeth until experiencing symptoms or receiving a diagnosis from their dentist. Understanding the signs, causes, and treatment options can help protect your teeth and alleviate associated pain.

Types of Bruxism

Sleep Bruxism (Nocturnal)

Sleep bruxism occurs during sleep and is often more severe than awake bruxism. People are typically unaware they're grinding until informed by a sleep partner or dentist. It's classified as a sleep-related movement disorder and is often associated with sleep arousal patterns. Sleep bruxism can cause significant tooth damage because grinding forces can be 2-3 times stronger than normal chewing.

Awake Bruxism (Diurnal)

Awake bruxism involves jaw clenching or teeth grinding while conscious, often during periods of concentration or stress. Unlike sleep bruxism, people can become aware of and consciously stop this behavior. It's frequently triggered by stress, anxiety, or intense focus and is often described as a nervous habit.

Signs and Symptoms

Common Symptoms Include:

Morning jaw pain or stiffness: Waking with a sore, tired jaw that feels tight or locked
Headaches: Dull, tension-type headaches particularly in the temples upon waking
Tooth damage: Worn, flattened, fractured, or chipped teeth
Tooth sensitivity: Increased sensitivity to hot, cold, or sweet foods
Cheek damage: Damage to the inside of cheek from chewing
Earache: Ear pain without infection (due to jaw joint proximity)
Sleep disruption: Poor sleep quality or partner disturbance from grinding sounds
Facial pain: Chronic facial pain or temporomandibular joint (TMJ) disorders

Causes and Risk Factors

Psychological Factors

Stress and anxiety are the most common triggers for bruxism. Increased stress levels correlate with more frequent and severe grinding episodes. Anger, frustration, competitive personality types, and coping with stressful situations often manifest as teeth grinding or clenching.

Physical Factors

Sleep disorders: Sleep apnea, snoring, and sleep talking are associated with increased bruxism
Bite problems: Malocclusion, missing teeth, or crooked teeth can contribute
Medications: Certain antidepressants (SSRIs) and stimulant medications increase risk
Age: More common in children but often resolves with age
Genetics: Bruxism tends to run in families

Lifestyle Factors

Caffeine consumption: High caffeine intake, especially in evening hours
Alcohol use: Alcohol consumption increases bruxism episodes
Smoking: Tobacco use doubles the risk of teeth grinding
Recreational drugs: Particularly stimulants like cocaine or MDMA

Treatment Options

Dental Appliances

Night guards (occlusal splints) are the most common treatment. Custom-fitted by your dentist, these protective devices worn during sleep cushion your teeth and prevent grinding damage. While they don't stop bruxism, they protect teeth from wear and reduce jaw muscle strain. Over-the-counter guards are available but custom guards provide better fit and protection.

Stress Management

Counseling or therapy to address underlying anxiety and stress
Relaxation techniques: meditation, progressive muscle relaxation, yoga
Cognitive behavioral therapy (CBT) to modify behavior patterns
Biofeedback training to increase awareness of jaw clenching

Lifestyle Modifications

Reduce or eliminate caffeine, especially after 2 PM
Limit alcohol consumption, particularly before bedtime
Avoid chewing gum or hard foods that stress jaw muscles
Establish a relaxing bedtime routine to reduce sleep bruxism
Apply warm compresses to jaw muscles before bed
Practice jaw exercises to relax muscles

Dental Treatments

If bruxism is caused by bite problems or misaligned teeth, your dentist may recommend orthodontic treatment, tooth reshaping, or crowns to correct alignment. Severe tooth damage from grinding may require restorative dentistry including fillings, crowns, or root canals.

Medical Treatments

Muscle relaxants: Short-term use before bedtime in severe cases
Botox injections: Weakens jaw muscles to reduce grinding force
Medication adjustment: If bruxism is medication-induced, discuss alternatives with your doctor
Sleep apnea treatment: Treating underlying sleep disorders often reduces bruxism

When to See a Dentist

If you experience any of these symptoms, schedule a dental appointment:

Teeth that are worn, damaged, or sensitive
Persistent jaw pain, clicking, or limited movement
Frequent morning headaches or facial pain
Sleep partner reports grinding sounds
